Optimal Inspiratory Pressure for Facemask Pressure-controlled Ventilation in Children: Study Using Detection of Gastric Insufflation Using Ultrasonography of the Antrum and Epigastric Auscultation
In Brief
A clinical study evaluating Mask ventilation and Rocuronium for Child and Anesthesia. Completed, enrolled 120 participants across 1 site.
Detailed Summary
The purpose of this study is to find an optimal inspiratory pressure to provide adequate tidal volume and prevent gastric insufflation in pediatric patients. The children under 5 years old are randomly assigned to muscle relaxation group and non-relaxation group. For muscle relaxation group, routine anesthesia induction is performed with muscle relaxant and mask ventilation is started by pressure-controlled mechanical ventilation. Gastric auscultation and abdominal ultrasonography are performed simultaneously during mask ventilation to detect inflow of air. Initial inspiratory airway pressure is 10 cmH2O and increased gradually by 2 cmH2O until gastric insufflation is detected by either of two methods. Tracheal intubation is done after detection of gas. For non-relaxation group, mask ventilation is performed in a same manner, without muscle relaxant. After detection of gas by any of the two methods, rocuronium 0.6 mg/kg is administered and tracheal intubation is performed.

Timeline
Interventions
Mask ventilation is performed after administration of rocuronium or not. Initial inspiratory pressure is set as 10 cmH2O and increased gradually by 2 cmH2O until gastric insufflation is detected by either of two methods. Tracheal intubation is done after detection of gas.
Rocuronium 0.6 mg/kg is injected before mask ventilation in muscle relaxant group or after finish of study in non-relaxant group.
